Cancer symptoms in adults

There are several types of cancer with different symptoms. In this article we will discuss a total of 18 cancer symptoms adults, so you can recognize them.

Cancer facts

  • Cancer is the second leading cause of death after heart disease.
  • A significant percentage of newly diagnosed cancers can be cured.
  • Cancer is more curable if diagnosed early. Although some cancers occur completely without symptoms, the disease can be particularly devastating if you ignore the symptoms because you do not believe that these symptoms could be cancer.


Skin cancer: Symptoms

Development of skin cancer

Excessive exposure to the sun is the main risk No. 1 for the development of skin cancer. The ultraviolet rays have different effects on the skin. The sun has had a very positive influence on us. For example, sunlight causes the formation of vitamin D, which is so important for our bones. The sun is also important for our psyche. When the sun is shining, we feel more active and energetic and our mood is rising.  A certain tan of our skin is usually associated with health and well-being. Tanning our skin after prolonged exposure to UV radiation is actually a protective mechanism.
If this protection is broken, i.e. the skin is exposed to UV rays for several hours, sunburn occurs, possibly with blistering. Extreme radiation finally kills skin tissue from.


Basal cell carcinoma

Basal cell cancer is the most common of all skin cancers. It occurs most frequently in the sixth decade of life. Typical for him is his slow growth, usually over decades. There is no precancerous stage here. This cancer does not form metastases, but can grow quite deeply or show a pronounced surface growth. It always occurs in the places that are most exposed to the sun, e.g. on the nose, lower lips, neck and hands. The best form of treatment for this skin cancer is surgical removal.

Intestinal cancer: symptoms

Colon cancer is one of the most common cancers in Germany. Every year more than 50,000 people fall ill with this insidious disease. If colorectal cancer is diagnosed early, it is easily treatable and often curable. For this reason, there is a screening test for colorectal cancer, which is free of charge for men and women from the age of 45.

Why colorectal cancer?

There are no clear causes of colorectal cancer. If colorectal cancer is more common in the family, there is a certain predisposition to this disease and the risk of developing it increases. Dietary habits also play a role that should not be underestimated. If you eat a diet rich in dietary fibres, i.e. if you eat a lot of vegetables, fruit and wholemeal products, the time the food remains in the intestine will be reduced. If food remains in the intestine for too long, toxins are produced that can cause cancer. Other risk factors are colon polyps, which are considered a precursor of colon cancer, and colitis ulcerosa (inflammation of the colon mucosa).

Lung cancer: symptoms

the bronchial carcinoma

In Germany, lung cancer is the most frequent cause of tumour-related death in men and the third most frequent in women. Therefore it is all the more important to inform yourself about the risk factors. Smoking is the first priority here and it is essential to raise awareness of the dangers, especially among adolescents and young adults. Non-smoker protection should also be promoted, as statistics show that some 400 people die every year as a result of involuntary non-smoking.


How does a bronchial carcinoma develop?

At the beginning of the 20th century bronchial carcinomas were still extremely rare. They did not increase dramatically until the 1940s and 1950s and have been at the forefront of deaths as a result of tumor-related diseases since the 1960s. Most patients are between 50 and 70 years old. Cigarette consumption was clearly identified as the main cause of this type of cancer. Cigarette smoke contains many carcinogenic substances, which usually only form after combustion and thus enter the lungs. Less than 10 percent cannot be linked to smoking. Other causes are e.g. infections (tuberculosis) or toxic substances (e.g. asbestos, nickel, chromium) at the workplace or in the home.

The bronchoscopy

If lung cancer is suspected, a bronchoscopy is essential. A flexible tube is pushed over the nose into the trachea and into the bronchi. With an optical device attached to this tube, the doctor can see the condition of the mucous membranes. This device can also be used to take a tissue sample (biopsy), which can then be examined microscopically for any tumour cells. During the same examination, the doctor can also aspirate secretions from deep bronchial sections and test them for cancer cells under the microscope.

Prostate cancer: The symptoms

Prostate cancer symptoms in adults

The prostate is usually scanned from the rectum in a manual examination with the man standing, leaning forward. The doctor bypasses the largest part of the organ with his finger and can thus assess the size, shape and surface quality. In the initial stage, prostate cancer can be palpable as a small, hard, demarcable lump. In the advanced stage, humps on the surface and an indistinguishable tumour can be detected. However, a physician will never base his diagnosis on the palpation alone, but will additionally determine the serum concentration of the prostate-specific antigen (PSA). In addition, the prostate can be evaluated by ultrasound using a probe inserted into the rectum.

Why gastric carcinoma?

The causes for the development of gastric cancer have not been clearly clarified. However, there are certain efactors that increase the likelihood of suffering from this disease. For example, there is an increased risk if a family member already suffers or has suffered from gastric carcinoma. Stomach ulcers that have existed for a long time and do not heal are also pathogenic. Furthermore, gastric polyps and gastritis (atrophic gastritis) are also problematic.

Earth rays and cancer

It is often discussed whether geopathic stress (earth rays, water veins, electrosmog) can lead to cancer. Certainly these stresses are not the sole triggers, but cancer-promoting factors, such as poor nutrition, lack of exercise, environmental toxins, etc., can multiply among themselves. If there is a bad place to sleep, the body can no longer regenerate at night and our immune system is thus constantly in constant use.
The most important symptoms of geopathic stress are: restless sleep with longer waking periods, nightmares, sleeplessness, chronic complaints that do not improve despite treatment, muscle tension, anxiety, depression, cardiac arrhythmia, concentration disorders, etc.

Meanwhile, there are numerous institutes and associations that deal with rod walking and earth rays and that can establish contacts with corresponding experts.

Cancer symptoms: General

Cancer does not give most people symptoms or signs that point exclusively to the disease. Unfortunately, any complaint or symptom of cancer can also be explained by a harmless condition. However, if certain symptoms occur or persist, a doctor should be consulted for further evaluation. Some common symptoms that can occur in cancer are as follows:

Continuous cough or blood-soaked saliva

These symptoms usually represent simple infections such as bronchitis or sinusitis. They could be symptoms of lung, head and neck cancer. If you have coughing for more than a month or with blood in the coughing up mucus, you should consult a doctor.

A change in intestinal habits

  • Most changes in intestinal habits are related to your diet and fluid intake.
  • Doctors sometimes see pencil-thin stool associated with colon cancer.
  • Cancer occasionally leads to persistent diarrhea.


Some people with cancer feel that they need a bowel movement and still feel that way after the bowel movement. If one of these abnormal intestinal complaints lasts longer than a few days, it must be evaluated.

A significant change in intestinal habits that cannot be explained simply by a change in diet must be evaluated.

Blood in stool

A doctor should always examine blood in the stool.

  • Haemorrhoids often cause rectal bleeding, but because haemorrhoids are so common, they can occur in cancer. Therefore, even if you have hemorrhoids, you should have your entire intestinal tract examined by a doctor if you have blood in your stool.
  • For some people x-ray examinations may be sufficient to clarify a diagnosis. Colonoscopy is usually recommended. Routine colonoscopy, even without symptoms, is recommended if you are 50 years old.
  • Some times when the source of bleeding is completely clear (e.g. recurrent ulcers), these studies may not be required.


Unexplained anemia (low blood count)

Anemia is a condition in which people have less than the expected number of red blood cells in their blood. Anemia should always be examined.

There are many types of anemia, but blood loss almost always causes iron deficiency anemia. Unless there is an obvious source of ongoing blood loss, this anemia must be explained.

Many cancers can cause anemia, but colorectal cancer is the most common cause of iron deficiency anemia. The evaluation should include an endoscopy or x-ray of the upper and lower intestinal tract.

Breast cancer: breast lumps or discharge

Most breast lumps are non-carcinogenic tumors such as fibroadenomas or cysts. But all lumps of breast must be thoroughly examined.

A negative mammography result is usually not sufficient to assess a breast lump. Your doctor must determine the appropriate x-ray study, which may include an MRI or ultrasound of the breast.

Generally, diagnosis requires a needle aspiration or biopsy (a small tissue sample).
Discharge from the breast is common, but some forms of discharge may be signs of cancer. If the discharge is bloody or only from a nipple, a further evaluation is recommended.

Women are recommended to examine the breast themselves monthly.

Testicular nodes

Most men (90%) with testicular cancer have a painless or unpleasant lump on the testicle.

Some men have enlarged testicles.

Other conditions, such as infections and swollen veins, can also cause changes in your testicles, but each node should be evaluated.

It is recommended that men examine the testicles themselves monthly.

A change in urination

Urinary tract symptoms may include frequent urination, low urine levels and slow urine flow or a general change in bladder function.

These symptoms can be caused by

Urinary tract infections

(mostly in women) or in men by an enlarged prostate.

Most men suffer from harmless prostate enlargement with increasing age and often have these urinary tract problems. These symptoms may also signal prostate cancer.

Men with urinary tract symptoms need further examination, possibly including blood tests and a digital rectal examination. The PSA blood test, its indications and the interpretation of the results should be discussed with your doctor.
